Aluminium professional drill for precision drilling in soft and long-chipping materials with a strength up to 600 N/mm² (e.g. aluminium and aluminium alloys ≤ 10% Si, zinc, copper, thermosetting plastics).

Precise drilling

The stable twist drill bit in short design ensures precise drilling

Self-centring

The split point ensures excellent centring effect even on round materials, eliminating the need for centre-punching or piloting

Long service life

HC (high-speed cutting) finish and the associated precise rake ensure consistent drill hole quality while ensuring a high degree of precision and a long service life

Excellent chip removal

The plain spiral groove ensures excellent chip removal from the drill hole

Product packaging made of 100 % PCR (recycled plastic from household waste), 100 % recyclable and Cradle to Cradle Certified^® Bronze

The packaging unit defines the number of articles in one packaging. In the catalog segment you can choose from different packaging units if a pop-up menu is displayed.

Just leave the field empty if you don't know the packaging unit when directly entering the article number in the shopping basket or when importing with Easy-/VarioScan. The packaging unit will be determined automatically.

The article number is made up of the following: VVVVAAABBB
VVVV = 4 digits for prefix number (please note that the first digit is currently always 0)
AAA = 3 digits for dimension part 1
BBB = 3 digits for dimension part 2

Example article number structures:
Example 1: Screw with dimensions of 4x10 mm:
VVVVAAABBB
00574 10 (2 spaces between the 4 and the 10)

Example 2: Screw with dimensions of 10x20 mm:
VVVVAAABBB
005710 20 (1 space between the 10 and the 20)

Example 3: Flat washer with an internal diameter of 6 mm:
VVVVAAABBB
04076

Price per packaging unit (PU):
The displayed price is always in line with the displayed packaging, if the PU is 250 the price for 250 units, if the PU is 300 the price for 300 units.

Price with price key representation (PSL):
The price always applies to a quantity ruled through the price key:
Price for 1 unit
Price for 100 units
Price for 1000 units

The quantity shows the number of pieces or units of measure contained in the order or delivery for the respective article.

In contrast to sales packaging and secondary packaging, the disposal costs for chemical-technical products are shown separately. The breakdown of the individual costs can be found on the relevant products and also in the shopping cart, as well as in our General Terms and Conditions (GTC).
